Unit Substation

The CEEG compact substation integrates high-voltage switchgear, distribution transformer, and low-voltage switchgear, suitable for both indoor and outdoor use. The packaged substation features strong integration, a small footprint, low investment, and easy installation and maintenance. Rated voltages: 6KV, 10KV, 35KV. Enclosure protection ratings: IP54, IP33, with custom solutions available for special requirements.

The CEEG pad-mounted substation transformer integrates the high-voltage unit, distribution transformer, and low-voltage unit. The simplified configuration of the high and low voltage units makes it smaller in size and lower in cost compared to a prefabricated unit substation, and it does not have issues with heat dissipation. Transformers can be customized to customer requirements, including dry-type, oil-type, and amorphous alloy transformers.

To reduce the overall cost of solar power plants and improve efficiency, CEEG introduces a complete photovoltaic substation composed of grid-connected inverters, transformers, high and low-voltage switchgear, and cabinets. This 50Hz 0.4-35KV three-phase AC PV system offers DC distribution, inversion, step-up, monitoring, and communication functions. It serves as a perfect alternative to the traditional "inverter room + step-up station," making it ideal for both distributed and centralized power generation.

The CEEG prefabricated modular substation (e-house) is a modular and combinable electrical equipment solution. It includes transformers, high-voltage switchgear and control equipment, low-voltage switchgear and control equipment, internal wiring, metering, compensation, arresters, and other auxiliary equipment, all configured within a common enclosure or set of enclosures. This complete substation is tested and commissioned according to relevant standards. Various enclosure options are available, including non-metallic and containerized types.

Turnkey Solution
CEEG integrated energy storage booster and converter unit integrates photovoltaic inverter, transformer, and switchgear in one unit, fully tested at the factory, save on-site installation and commissioning time. The product demonstrates strong resilience even in harsh environment. Available in 6kV to 35kV, with dry type or oil-immersed options. Maximum single-unit capacity can reach up to 10MW.

CEEG's mining flameproof transformer substation consists of a high voltage vacuum switch or high voltage load switch, a dry type transformer, and a low voltage protection box or low voltage feed switch. It is designed to provide stable power in environments such as mines and tunnels where there is a risk of explosion due to methane mixed gas and coal dust, but no gases or vapors that corrode metals or damage insulation.
